Choosing a Baby Monitor

There are lots of different models of these devices, much easier life for young families. We will try to understand what is the difference between modern baby monitors. The main problem in using baby monitors could be interference in the radio signal between the two parts of the device or its suppression due to obstacles, which often are the walls. Baby monitors signal is clocked at 2.4 GHz. The problem is that devices are wi-fi, Bluetooth also use this frequency and can greatly affect signal quality.

However, there are models of baby monitors, allowing transmission of coded radio signal, thereby virtually eliminating any interference from other devices. Remains an obstacle for the signal to create a wall. There is a coded signal will not do, but you can pick up a model baby monitors with the most appropriate signal strength. Modern baby monitors are manufactured with capacity ranging from 100 to 500 mW, which corresponds to the work of 100 to 500 meters in line of sight. The simplest model can "break" only one wall, when the model output of 500mW "punch" Three walls of the house.

Next Unlike the considered devices is power supply options. Usually the parent and child modules are fed from either the network or from an independent source (batteries, batteries). Powerful versions of devices are powered from the network, or from powerful batteries, such as automotive. As an independent power supply is better to use "finger" batteries. Their lifespan is large enough, as they are easy to replace and find. Also, baby monitors distinguished by the monitor and its size. Since the video signal is transmitted with a resolution of 380 tv lines, then on a smaller monitor, the picture will look better, but on a larger monitor, it will be easier to watch. Almost all models have a connector for the parent unit to your tv or computer. It will be convenient because you can watch tv and watch over the baby at a time (the tv "PIP") or remote control to switch from watching tv to watch the baby.
